Welcome
Thank you for purchasing a Hotone product.
Please read this manual carefully to get the most out of your Ampero II Stomp.
Please keep this manual in a safe place for further reference.
Please read this manual carefully. It contains information regarding the proper use of this product and other important information.
DES I GN IN S PIRATION

Definitions
Effects Chain
The effects chain (or simply “chain”) shows the current internal signal routing/effect procession including current effects chain
type, signal routing, current effects and effects combination, etc.
Ampero II Stomp features two effects chains with flexible serial/parallel options.
Effect Slot
Effect slots (or simply “slots”) are spaces located on an effects chain for adding effects. Ampero II Stomp features 6 slots on one
effects chain, 12 slots in total.
Module
Ampero II Stomp employs 13 kinds of effects, each kind is called an “effects module,” or simply “module”. There are several
effects available in each module. To use an effect, add a module to an empty effect slot, and then pick one effect in the module.
There are also some modules used for signal routing only.
Parameter
Variables that determine the application of an effect are called “parameters”. If we imagine each slot as a separate effect pedal,
then each parameter would be a knob on that pedal.
Node
The beginning/end of an effects chain or the intersection of two effects chains is called a “node”:
•Input node is the beginning of an effects chain that sets signal input source;
•Output node is the end of an effects chain that determines where the signal goes;
•Split node splits one effects chain into two, sending the signal to two effects chains;
•Mixer node combines two effects chains into one.
Patch
The ON/OFF status and current module/effect of each effect slot, parameter settings and related controller/expression pedal
settings are stored in units called “patches”. These are your “tones.” Use patches to recall, edit, and save your favorite tones.
Bank
A set of 3 patches is called a “bank”. Ampero II Stomp has a total of 100 banks, which means, you have up to 300 fully
editable/savable patches. If you made a factory reset, the first 99 patches (factory preload patches) will be restored.
Cleaning
Use a soft cloth to clean the panels if they become dirty. If necessary, slightly moisten the cloth. Never use cleansers, wax, or
solvents such as paint thinner, benzene or alcohol.
Malfunction
•If the unit should malfunction, disconnect the AC adapter and turn the power OFF immediately.
Then, disconnect all other connected cables. For:
- Power adapter malfunction
- The unit or power supply emits an odor
- Liquids or foreign objects entered the unit
- The unit has other obvious signs of malfunction (e.g. won’t turn on, knobs won’t work, won’t produce sound, etc.)
•Prepare information including the model name, serial number, specific symptoms related to the malfunction, your name,
address and telephone number and contact the store where you bought the unit.

to add an effect module (or simply “module”), and pick one effect contained in the module.
Ampero II Stomp features 13 effects modules as listed below:
• DYN: Dynamic effects like compressor, boost, noise gate, etc.
• FREQ: Filter-based effects like low/band/high pass filter, envelope/auto filter, pitch shift/detune, octave, etc.
• WAH: Wah pedal
• VOL: Volume pedal
• DRV: Overdrive and distortion
• AMP: Amp modeling effects
• PRE AMP: Preamp effects incl. acoustic/bass preamps
• CAB: Cabinet simulations
• IR: For loading built-in factory IRs (incl. acoustic IRs) and user Irs
• EQ: Equalizers
• MOD: Modulation effects
• DLY: Delay effects
• RVB: Reverb effects
There are also 3 FX Loop related modules:
• FX SND: FX loop send module for sending signal to external devices via unit’s FX loop send jack
• FX RTN: FX loop return module for receiving signal from external devices via unit’s FX loop return jack
• FX LOOP: FX loop module for inserting external effects to an effects chain via unit’s FX loop jacks
Effect Slot Status
There are three slot status shown as below:
• Empty slot - the slot acts like a cable
• Slot off - the slot is bypassed, and the module in the slot doesn’t work
• Slot on - the slot is on, the module in the slot is working
The next texts will show you how to edit an effects chain.
Input Node Setup
Select an input node and the parameters will come up as shown below:
SOURCE lets you select an input signal source of current effects chain:
•Input: Sets the effects chain input source to the unit’s input jack
•FX RTN: Sets the effects chain input source to unit’s FX loop return jack
•USB 3/4~7/8: Set the effects chain input source to USB audio output 3/4~7/8, which is convenient for reamping (check USB

There are two selections available for chain B only:
•None: no input, then chain B will turn gray to indicate chain B not working:
•Chain A: Receives outputs from chain A, in this case, the chain A and B connects in series (see Effects Chain Types section
on for details):page 14
INPUT CH lets you select the signal input channel:
•L/R: For FX loop return jack, the left channel is connected to tip conductor and the right channel is connected to ring:
For USB outputs, even number stands for left channel (3, 5, 7) and odd number stands for right channel (4, 6, 8)
•Sum: Sums input signal to mono
•Stereo: Receives L/R stereo inputs
LEVEL lets you adjust input level from Mute~-60dB~+20dB. Default is set to 0dB (unity gain).
Output Node Setup
Select an input node and the parameters will come up as shown below:
OUTPUT TO lets you decide where the output signal goes:
•Output: Sets the signal output to unit’s output jacks (and phones jack)
•FX SND: Sets the signal output to unit’s FX loop send jack
•Chain B: For chain A only, which lets you connect chain A and B in series (see Effects Chain Types section on for details) page 14
•None: For chain B only, in this case, chain B’s output node won’t work
OUT LEVEL lets you adjust output level from Mute~-60dB~+20dB. Default is set to 0dB.
PAN lets you adjust output signal stereo panning. The range is L50~Center~R50, default is set to Center.
Parallel
The chain A and B are fully parallel (won’t affect each other),
When you load an empty patch, the default effects chain
type is a special parallel state that only chain A is working.
Split-Mix
An input signal will be split into two and sent to both chain A
and B, then mixed into one and sent to one output:
Effects Chain Types
Ampero II Stomp supports various effects chain types:

Note: When you set OUTPUT TO to FX SND, the VOLUME knob will not work. In this case, use OUTPUT LEVEL to
control the output volume.

Serial
Chain A and B are connected in series (head to tail):
The touch screen lets you easily change effects chain types within a few taps and drags.
Next we’ll take parallel type as an example to show how to change chain types:
Change To A/B-Y
Drag and drop output node of chain B on chain A depending on your needs:
Change To Y-A/B
Drag and drop input node of chain B on chain A depending on your needs:
Change To Serial
Drag and drop input node of chain B to the output node of chain A:
Change To Split-Mix
Drag and drop input and output nodes on chain A (between input and output nodes) depending on your needs:
You can also operate by using Main Knob:
Turn Main Knob to a node – hold Main Knob to “pick up” a node – turn Main Knob to move the node to a place on chain A you
need – press Main Knob to “put down”
Y-A/B
An input signal will be split into two and routed to two
outputs via both chain A and B:
A/B-Y
Two signal inputs will be mixed into one and sent to one
output:

Using Effects Chain Templates
You can load built-in effects chain templates for quick setup, or save all your current effects chain settings (incl. chain type and
node settings) as a user effects chain template.
Press button and the effects chain template menu will appear:
Factory Template submenu lets you choose from one effects chain type mentioned above. In factory templates, all split nodes are
set between input node and slot A1, all mixer notes are set between slot A6 and output node; all node settings are set to default.
User Template lets you choose from one of five user templates (see Save Effects Chain Templates section on ): page 18
All templates are global data that won’t change when changing patches. You can load them anytime in any patch.
Split/Mixer Node Settings
When using two chains, for best possible result, you need to carefully setup split and mixer nodes.
The texts next will show you how to setup split and mixer nodes.
Split Node
Select a split node and the parameters will come up as shown below:
MODE lets you select a signal separation mode:
•Mode I
In this mode the split node outputs same signals to both chain A and B as node input signal. If the split node is between slots
containing effects with same signal I/O processing (all mono or stereo effects), this mode is recommended.
Use LEVEL TO A/B to set output level to A/B chains from 0~100, default is set to 100.
k
Notice the parameter difference between Mode I and II
Please note:
If you’re mixing mono/stereo effects in slots around split node, the actual output may differ from what you expected. For
example, use a stereo delay in the slot right before the split node with different delay settings on L/R channels, then use two
mono filters in the slots right next to split node on both A/B chains, the result is you can only hear the delay settings on left
channel. This is because effects with mono input use left channel of input signal ONLY.
For detailed signal I/O processing, please check Effects List ( ). page 41

•Mode II
In this mode the split node will convert node input signal into dual mono signal and send it to both chain A and B. If the split
node is between slots with mixed mono/stereo effects (e.g. one stereo effect in the slot right before the split node, two mono
effects in slots right next to the split node on both chains for processing L/R outputs of the stereo effect), this mode is
recommended.
Use BALANCE A/B to set output signal content (L/R ratio of node input signal) from L50 ~Center~R50, default is set to
Center. Fine tune the parameter depending on your needs:
•BALANCE set to L50/R50 means only left/right channel of input signal will be sent to the slots next to split node
•BALANCE set to a value in between means a mixed signal will be sent to the slots next to split node; the value sets the
mixing ratio, set to Center means mixing ratio=1:1
Use LEVEL TO A/B to set output level to A/B chains from 0~100, default is set to 100.
Mixer Node
Select a split node and the parameters will come up as shown below:
Use A/B LEVEL to set input level from A/B chains. The ranges are all 0~100, defaults are all set to 100.
Use A/B PAN to set input signal stereo panning from A/B chains. The ranges are all L50~Center~R50, defaults are all set to
Center.
When you mix A/B chain signals, output may sound very sharp/thin/weak/muddy, even left and right outputs are L/R not
balanced, this may be caused by signal phase issue. If mixed output sounds abnormal, you can set B POLARITY to reverse
chain B signal phase and see if the problem solved or not. B POLARITY is set to Normal by default. Sometimes reversing chain
B’s phase may surprise you.
Use MASTER to set output level of mixer node. The range is 0~100, default is set to 50.
Turn on MASTER SUM switch to sum mixer node output to a dual mono output. Default is set to Off.
Please note:
Setting split node to Mode II only will NOT lead to a result like “left output is a kind and right is another”, since extra
output/mixer nodes settings are needed.
Please note:
1. When using stereo effects, in some cases, turning on MASTER SUM may lead to an abnormal output or even no output,
this may be caused by L/R phase cancellation.
2. Please adjust A/B LEVEL and MASTER carefully to prevent signal clipping.

Please note:
Different effects have different processor power requirements. So, as more and more modules/effects are added, some of
the module/effect names will turn grey and become unavailable. This indicates remaining processor power is not
enough to handle these modules/effects, which is normal.
